The artwork created by artist Chris Fox, titled Interloop, was commissioned to top off a multimillion-dollar redevelopment of Wynyard station, in the heart of the city’s financial district. It’s already been called by several people online as a “stairway to heaven”.

Four combs and 244 steps from the previous escalators have been refashioned into a soaring crisscrossing tangle reminiscent of an Escher puzzle.

The escalators had been in place for 80 years. Following the 1987 fatal fire at London’s King’s Cross station, which began under a wooden escalator, the devices fell out of favour. The Wynyard escalators were fire retardant but a much more everyday problem was the number of high heels which became stuck in the wooden wedges on the steps.

“I remember going to my first job as a 17 year old and getting my stilettos caught in those grooves,” said a social media user.

With the station being redeveloped, the decision was made to replace the escalators as well.

“While the new modern escalators at Wynyard station are safer, more reliable and reduce the cost of maintenance, it was important to recognise the heritage status of Railway House and the York Street lobby as well as the iconic wooden escalators which were among the last of their kind in the world,” Transport for NSW coordinator general, Marg Prendergast, said.

“In addition to the impressive heritage-inspired artwork, the heritage significance of the building is recognised in the architectural design of the upgraded lobby as well as a historic photo of the original escalators from the 1940s which customers can see as they travel down the new escalators.”

The striking reuse of the old escalators appears to have won approval.

“This is best thing the state has done in years,” said one person on social media.

“Travelled up and down those escalators so many times in my life, glad they haven’t been relegated to the tip and have been made a feature,” said another.

Others were more succinct: “Just incredible,” said a Twitter user.

The completion of the Wynyard station upgrade comes as another big transport project was revealed. The first completed section of Sydney’s new CBD tramline can now be seen as barriers were dismantled along a section of George St.

Pedestrians can now walk across the tracks in the CBD between Market and Park streets, one of Sydney’s busiest shopping areas.

But you’ll still have a long wait for a tram. Much of the rest of the network is still under construction and the first tram in service won’t pick up passengers until 2019.
